Abstract: The method for producing an optical member of the present invention includes: Process (1) of applying a first resin to a substrate; Process (2) of applying a second resin to at least one of the first resin and a die; Process (3) of pushing the substrate to the die with the first resin and the second resin in between to form a resin layer including on a surface thereof an uneven structure; and Process (4) of curing the resin layer to provide a polymer layer. The die includes a surface after release treatment with a fluorine release agent. The first resin contains a resin component, and the resin component contains predetermined amounts of a (meth)acrylamide compound and a urethane prepolymer containing six or more functional groups. The second resin contains predetermined amounts of a reactive group-containing monomer, a fluorosurfactant, and a fluorine-containing monomer.
